I got a whole bunch over about a 10 year period and was just starting a new one so reread each one (in order) and started taking notes of anything I wanted to "keep" into the front of my new journal. I ended up with maybe 10 pages of ideas and quotes, etc. and after I'd finish with each of my old journals, I tore it up, destroyed it. It felt good to "boil it down" to the stuff that seemed important to me. Of course, I still have that "new" journal, even though it is now 5-10 years old, LOL. But I don't have many of the other ones I've started after that. I kept to rereading and copying info and then getting rid of some of the old stuff. I do that with "papers" and magazine articles, etc. that I save too now. Feels really good go be more lightweight :-)
